Description

deluxe focuser with index marks for fine focusing of CCD cameras and eyepieces

2 screws fix the focus position

M48 x 0.75 female thread on the telescope side and M48 x 0.75 male thread on the camera side

you also can use the focuser as a variable M48 (51mm to 91mm) extension

A true helical focuser like this TS Helical Focuser, works like a camera objective… when you turn the focusing ring, neither the lens nor the camera (or eyepiece and diagonal) rotate – The only motion is in and out.

The advantage of this helical focuser is the fine adjustment possible, in part due to the fine pitch of the focusing ring’s thread, and in part due to the large diameter of the ring.

In the case of the TS Helical Focuser, virtually backlash-free movement and graduated markings on the focuser allow repeatable return to the focus point simply by noting the focus position reading.
